oinOV conve er reference numeral 5 desigb D nates a roller shaft ivhich'pis iixed against rotational movement and suitably supported 1 at the ends. This shaftis provided intermediate its ends with the stator element ,6 `cfa motor, the electrical leads 7 from' the Y Wiring `.ofwhich `'extend -into the shaft 5 and yare conducted 'intog a suitable aperture fextending longitudinally of the shaft outl through the end thereof andthrough/a fit- I 'ting 8 and thence toa suitable" scurce'of elec trical energy. 4Shaft `5 also Acarries intermediate its ends an electro-magnet made up of apole piece 9 inthe formlof,arectangular hollen7 box and a second pole piece 10 in the form` of Aa partition*extendinglongitudinally of the shaft 'Within the box-like pole piece l9.v `lafindi'cate's relectrical windings around the Vplole piecev 9 and v1l designatesv a suitable l clover for the jvvindings', Vto Y protect the' Vsame and ,held in .placev inany desired manner.
